DOOR-CHEGK.

SPECIFICATION forming part of Letters Patent No. 290,526, dated December18, 1883,

Application tiled August l5, 1883., (No model.)

To all whom t may concern:

Be it known that I, JNo/V. BULGER, a citizen of the United States,residing at East Liverpool, county 'of Columbiana, and State of Ohio,have invented certain new and useful Improvements in Door-Checks; and Ido hereby declare the following to be a description of the same, and ofthe manner of constructing and using the invention, in such full, clear,concise, and exact terms as to enable any person skilled in the art towhich it appertains to construct and use the same, reference being hadto the accompanying drawings, which forni a part of the specification,the principle of the invention being herein explained, and thebest'inode in which Ihave contemplated applying that principle, so as todistinguish it from other inventions.

The object of this invention is to provide an improved form ofdoor-check adapted to maintain a door open at any desired point.

In the drawings, Figure 1 represents the docr-check applied as in use.Fig. 2 is a perspective View of the dooncheck. Fig. 3 is a centralvertical longitudinal section of saine.

The doorcheck consists of two parallel straight `iaws, A, united attheir front eX- tremities by a joining portion, al These jaws may be.formed at any suitable distance apart, corresponding to di'erentthicknesses of doors. This door-checlr is made as an oblong integraldevice adapted to rest freely on the floor and to beslid thereon atwill. The jaws and their j oining portion have sliding bearingthroughout their entire area, and are formed heaviest and broadest attheir bottom. They are respectively made so that in verticalcross-section they are in the outline of a right-angle triangle. Thispermits their inner sides to be substantially vertical, While theirouter sides incline outwardly from the top to the bottom. The sides ofthe door can thus have continuous bearing against the inner verticalsides of the jaws throughout the lattersheight and length; also, thedoor-check is formed of stable equilibrium, the broad base of itpermitting it to be moved freely in a sliding movement over the iioorWithout liability to be tipped over.

This doorcheck may be made of any kind of metal, or of glass, rubber,porcelain, or other material. It may be glazed, plated, or covered withcloth.

Vhat I claim is* The herein-described door-check, formed broad at thebase and tapering toward the top, the same consisting of the twostraight jaws A and the joining portion a, said parts having verticalinner sides and outer sides which incline outwardly from the top to thebottoni, substantially as set forth.

In testimony that I claim the foregoing to be my invention I havehereunto set my hand this 9th day of August, A. D. 1883.
